Chocolate cake is a food item that players can make with a Cooking level of 50. A regular cake yields 180 Cooking experience when baked; the addition of a chocolate bar or chocolate dust will grant an additional 30 experience. The cake heals a total of 1,248 life points, equally spread over three bites of 416 life points each. When one bite is taken out, it becomes a 2/3 chocolate cake. When two bites are eaten, it becomes a chocolate slice.

Chocolate cakes used to be a members-only item, even though all the ingredients were available to non-members. Since this made little sense, Jagex changed the chocolate cake to a non-members item.

Making a chocolate cake from scratch in the Lumbridge kitchen is a Lumbridge/Draynor hard task.

2/3 chocolate cake is obtained by eating a bite of a chocolate cake, and a Chocolate slice is what is left of a full chocolate cake after eating two bites. They have two and one uses left, respectively, each bite healing 416 life points.

It is not possible to add a chocolate bar to the 2/3 cake and slice of cake to create their respective chocolate cake items, nor can chocolate cake slices be recombined to make a full cake.
